Things You'll Need
Instructions
Insert the dongle into one of the USB ports. These are located in front of the PS3 console. If a red light appears on the dongle, it is properly connected.
Press the button on the dongle if the light blinks or does not turn on. When the guitar is not connected, the light will blink; when the guitar is connected, it will be a solid red.
Press the button on the guitar that says "PS" on it. Notice the red light on the guitar begin to flash as it searches for the dongle. When both lights are solid red, the guitar has been registered by the console.
